A Canadian rapper/singer/songwriter/producer, whose given name is Kevin Brereton. His stage name is pronounced /ˈkeɪ.ɒs/ "chaos," and the letters stand for "Knowledge of Self," although he has stated in interviews that the letters originally stood for "Kevin's Original Sound." Unlike many mainstream hip-hop artists, k-os generally does not focus on violence and sexual bravado, but rather introspective lyrics, love, and spirituality. While he still sometimes mentions the streets, he does so in a more philosophical, reflective way. Some of his best known songs include "Superstarr, Pt. Zero," "I Wish I Knew Natalie Portman," and "Crabbuckit."
Club DJ: Now we gonna play a joint from k-os, called "Superstarr, Part Zero!"
Club Kid: Huh? Who the hell is "chaos"?

Kill On Sight

If someone is KOS that means you devour them right when you see them no questions asked.
Level 126: "Sorry kid but your clan is KOS so I've got to kill you."
Noob: "But I just want to play the game man, come on I'm almost done with this quest..."

IMO and in many, the best Canadian rapper. Breaking away from the treachery of commercial hip hop and money making artistry, he excels the art to a form that is most earthly, and real. He can bring heavy NY sounding hip hop in one track, then soulful guitar (played by him) blues in another. A true artist in a world of few.
